G479 – Electroconvulsive therapy (ECT) cerebral - single or multiple - out-patient
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This fee code provides payment for single or multiple cerebral electroconvulsive therapy (ECT) sessions administered in an out-patient setting. The service includes the therapeutic application of electrical currents to the brain. Please note that Electrosleep therapy or Sedac therapy are not insured benefits and are not payable under this code.
When to Use
- Use G479 for the professional fee when performing ECT on an out-patient basis in a hospital facility.
- Use G479 when the patient is not admitted to the hospital, distinguishing it from G478 which applies to in-patient settings.
Common Pitfalls
- Billing G479 for in-patient ECT instead of G478 will result in rejection or audit recovery.
- Attempting to bill G479 for non-insured procedures like Electrosleep or Sedac therapy will lead to claim rejection.
Billing Tips
- Ensure you append the appropriate Hospital Out-Patient Special Visit Premium (U-series) if the ECT session meets the criteria for a special visit to the facility.
